This is essentially the same game as Gurumin: A Monstrous Adventure, except it’s a 3DS port with full 3D stereoscopic capabilities.
You play as a young girl who can see monsters that no one else can. It’s an action RPG where you use a giant drill and an arsenal of skills and items in order to defeat hordes of enemies and solve puzzles within plenty of dungeons. As you progress, you uncover pieces of furniture to give back to friendly monster in their village.
